Abstract (en)
[origin: WO2006129246A2] A light-source comprising at least one lighting unit (101) being arranged on a substrate (102) and a diffusing element (103) being arranged to receive and diffuse light emitted by said at least one lighting unit (101) is provided. The diffusing element (103) comprises a layer of non-woven fabric having a lower density at a side facing the lighting unit and a higher density at a side opposite to the lighting unit to obtain good diffusing properties.
